Mesa/Boogie DC5 manual REAR PANEL continued SLAVE, Speaker

REAR PANEL: (continued)

SLAVE:

This 1/4" jack and control provide a signal derived from the speaker jack. Perfect for using the DC-5as a master pre-amp, or additional power amps may be connected for more power when needed. Some players use this to derive an FX Send Signal and go

to other amps for their wet sound.

SLAVE

NOTE: Once a signal is taken from the SlAVE, it can not be inserted back into the FX Loop Return jack or a feedback loop will occur. Much like holding a microphone into the PA system’s cabinets...a loud high pitched squeal will occur.

SPEAKER:

One 8 ohm and two 4 ohm speaker jacks are provided. The DC-5is not very sensitive to speaker mismatches and will not be damaged by them, except that very low ohmage loads will cause the power tubes to wear faster. A single twelve-inch 8 ohm speaker should generally be connected to the 8 ohm output. When using two 8 ohm speakers, connect them both to the 4 ohm outputs provided (because the total load is 4 ohms in that case.)

4X12 cabinets may be 4, 8 or 16 ohms; if you are not sure of the impedance of your cabinet, you may need to remove the rear panel to see what the ohmage of the individual speakers are. MESA/Boogie 4X12 cabinets come standard wired to 8 ohms. They have four 8 ohm speakers wired in series-parallel. Some Non-Mesa4X12 cabinets are wired 16 ohms using four 16 ohm speakers. By wiring all four speakers in parallel, you can reduce the cabinet to an impedance load of 4 ohms (assuming the speak- ers are 16 ohms each.) No matter how unusual your speaker setup, it is always possible to get good performance. If you need two 8 ohm speaker jacks (in order to run two 16 ohm cabinets at the same time), you can use a Y-box and daisy-chain the cabinets together.

Feel free to experiment with the speaker jacks, trying different loads. Many great sounds and feels may be achieved by experimenting with different combinations of speaker impedance. Keep in mind the greatest clean headroom is always achieved with proper imped- ance loads...i.e. an 8 ohm speaker connected to an 8 ohm jack.

NOTE: Always use a load on the DC-5when playing, unless you are recording direct and have the silent recording switch set to the Mute position.
